类名称：XYSplineRenderer

XYSplineRenderer介绍

[英]A renderer that connects data points with natural cubic splines and/or draws shapes at each data point. This renderer is designed for use with the XYPlot class. The example shown here is generated by the XYSplineRendererDemo1.java program included in the JFreeChart demo collection:
[中]将数据点与自然三次样条曲线连接和/或在每个数据点绘制形状的渲染器。此渲染器设计用于XYPlot类。这里显示的示例是由xysplinerderdemo1生成的。JFreeChart演示集合中包含的java程序：
